If you're going to prioritize one thing for your brain health, make it this: regular aerobic exercise. Multiple large-scale studies show that aerobic exercise doesn't just keep your heart healthy-it directly impacts your brain structure. One year of aerobic exercise in older adults led to significantly larger hippocampal volumes and better spatial memory. Other trials documented that exercise actually slows age-related gray matter volume loss.
We found that a simple, guideline-based exercise program can make the brain look measurably younger over just 12 months. Many people worry about how to protect their brain health as they age. Studies like this offer hopeful guidance grounded in everyday habits. These absolute changes were modest, but even a one-year shift in brain age could matter over the course of decades.
A sweeping review of over 200 studies finds that aerobic exercises like walking and cycling offer the best pain relief and mobility gains for knee osteoarthritis. Compared to other types of exercise, aerobic training showed the strongest evidence across short- and long-term outcomes. All forms of exercise were found to be safe, but experts recommend making aerobic activity the foundation of treatment. Share:
